TO ALL WHOM IT MAY CONCERN:

` Be it known that I, JAMES `D. KrNcAIn, of Bowling Green, in the county of Perry, and State of Missouri, have invented a. new and useful Improvement in Gang and Breaking-Ploughs; and I do herebydeclare that the following is a full and clear description thereof, reference being had vte the accompanying drawings, and to the letters of reference marked thereon.

This invention relates, firstly, to a device for holding the plough or ploughs steadily in position, laterally and also down into th' g1ound,'during the operation of ploughing, the device being especially needed in and adapted to a breaking-plough, in the use of which the rough and uneven nature of new ground often causes great trouble in its guidance. -The invention relates, secondly, to the device for lifting the ploughor ploughf up out of the ground; and, thirdly, to the mode of attaching the ploughs to the frame. l

To enable those skilled in the art to make and use my improved plough, I will proceed to describe its construction and operation.

Figure 1, of the drawings, is a longitudinal section of the improved plough.

Figure 2 is a rearend elevation of it.

Figure 3 is a. plan.

The frame A, which sustains the ploughs,'is mounted on the wheels B B in much the usual manner of common 'gang-ploughs, the principal dilference being the construction of the wheels, which, in this instance, are made of the same height and somewhat larger in diameter than those usually employed.

The device for guiding and directing the plough or ploughs laterally is as follows, viz: There are two rockshafts or rollers, C C, which have their bearings in the top of the frame A. On the forward vends of theseV shafts or rollers are cranks or elbows c, and on the rear ends of them lare similar cranks or elbows c1L diametrically oppositethose at the forward end. The outer ends of the elbows c are connected, by means of the chains c2 with the lever O-,-which is in such convenient proximity to the seat S as to be operated by the driver while seated thereon. The outerends of the elbows cl are connected, by means of the chains c3, with the upper part of the plough-post D. Other chains c4 are attached to the said post D lower down, and also to the frame A, as an additional lateral stay for the ploughs, the latter chains being tight only when the ploughs are down in the ground. l

When the parts are thus arranged,and the ploughs are down in'the ground, the driver, by depressing the lever C', will raise the elbowsc and depress cl, and the chains c3 will, by the operation, be made to draw tightly on the post D, as shown in iig. 2, and at the same time the said chains will also draw down on the4 post D, as is also shown in tig. 2Q The effect of this will `be to steady and guide the plough laterally, and also to hold it down in the ground while atfwork.

The device for lifting the ploughs up consists'of the levers E, pivoted on the fulcrumfarms e e, the chains or rods E', which connect the plough-beamswith the back ends of the levers, and the spring-catch e', attached to the frame A immediately below the drivers seat, and a little in front thereof, so as to allow of its operation by his feet.A The fulcrnm-arms Ae e are simple L-shaped rods attached to the frame A. The upper or horizontal parts of these fulcrum-arms might form a continuous rod `across the machine from side to side.

Theattachment of the forward ends of the ploughbeams to the frame A is made by means of the clevis d, the undulating bar dl, and the stays d2. The undulating bar is a U-shaped rod, having its ends pivoted in the stays cl2, which are attached to the bottom` side of the frame A. The clevis d is attached to the forward end of the plough-beam in the usual manner. ,By this arrangement of the parts the lplough is enabled to run steadily in the ground, without reference to the'vertical undulations of the wheels, caused by theasperities of the surface of the eld, the undulations of the'bar cZ taking up that givenit bythe frame Awithout imparting it to the plough-beam.

Having described my invention, what I claim, is

1. The rock-shafts orrollers C C and their cranks or elbows c c1, thelevcr C', and the chains c3, when` combined-with the post D of the plough, as and for the purposesherein set forth and described.

42. I claim the combination and arrangement of the levers E,n the chains Yor rods E, the fulcrum-arms e `e, i

and the spring-catch, substantially asdescribed and set forth.

3. I claim the attachment of the plough-beams to the frame A by means of the device d dl d, substantially ns described and set forth.
